Power Detector; Common Queries - Comtech EF Data LPOD PS 1.5 Installation And Operation Manual

LPOD C-, X-, or Ku-Band Outdoor Amplifier / Block Up Converter (BUC)
Serial Interface Operation
• Redundancy waveguide switch position fault (applies to redundancy mode operation only).
• Redundancy inter-unit link fault (applies to redundancy mode operation only).
• Low Noise Block Down Converter (LNB) current over limit.
The following parameters can be user defined to report an alarm condition, a fault condition, or the parameter can be ignored
completely by masking it:
• RF amplifier low output power (user adjustable value).
• Internal reference oscillator unlocked.
• *LNB current outside specified window.
• *LNB voltage out of tolerance.
*If this parameter generates a fault condition, the RF output will be muted.

5.2.5 Power Detector

A power detector is provided to monitor the output power. It has a useful range of over 20 dB, referenced to the unit's rated P1dB
point. Its value can be read by executing the RMS query. The test data supplied with each unit gives an indication of the accuracy
and flatness of the power monitor over the frequency band of operation.

5.2.6 Common Queries

The most common queries are:
• RMS (Retrieve Maintenance Status) – Returns voltages, fan speeds, heatsink temperature, output power monitor reading,
etc.
• RCS (Retrieve Configuration Status) – Returns current attenuation, mute, amplifier, online, etc. status.
• RAS (Retrieve Alarm Status) – Returns current alarm or fault status.
Full details are available in Section 5.4.
